However, powering these systems remains a major challenge owing to biocompatibility concerns and the environmental impact of conventional batteries. Here we present a bioresorbable magnesium–molybdenum trioxide (Mg–MoO3) paper battery that delivers high electrochemical performance under physiological conditions and safely degrades over time. The battery provides a peak open-circuit voltage of 1.84 V and supports capsule-scale ingestible electronic systems incorporating bioresorbable power sources for two key gastrointestinal applications: battery-assisted radio-frequency identification tags for wireless medication tracking and capsule systems for electroceutical therapy. In vivo studies in swine models have demonstrated robust operation within the gastrointestinal tract and compatibility with clinically relevant use cases. This study establishes a foundation for safe, high-performance and bioresorbable power sources in biomedical electronics, enabling retrieval-free, eco-friendly devices that eliminate electronic waste in the gastrointestinal environment. This study presents a bioresorbable magnesium–molybdenum trioxide paper battery that delivers 1.84 V under physiological conditions and degrades after use. Validated in swine models, the platform powers battery-assisted RFID medication adherence tracking and capsule-based gastric electrical stimulation, establishing a foundation for retrieval-free bioelectronic medicine.","PeriodicalId":501699,"journal":{"name":"Nature Chemical Engineering","volume":"3 9","pages":"509-521"},"PeriodicalIF":29.7,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s44286-026-00443-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149014756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, membrane performance is still primarily evaluated against the permeability–selectivity trade-off originally developed for glassy polymers. In this Perspective, we argue that assessment of next-generation CO2 separation membranes requires expansion beyond this trade-off to consider a broader range of metrics, including inherent upper limits on selectivity and permeability, thickness-dependent permeance constraints, and effects of operating conditions such as CO2 partial pressure. Applying this expanded framework, we demonstrate that materials with high CO2 sorption or reaction affinity excel with dilute feeds that require high selectivity, whereas polymers and non-reactive liquids are needed at elevated CO2 partial pressures and for high-permeance membranes. We further identify potentially disruptive areas for future work and provide guidance for matching material classes to applications. Membrane-based carbon dioxide separations are expanding into a broader range of applications, driving the development of new materials and separation mechanisms.

Although numerous efforts have been made to degrade toxic organofluorine into non-toxic inorganic species to mitigate environmental risks, the vast fluorine resources embedded in waste streams remain underutilized. Here we introduce a flash-encapsulated fluorination method to sustainably recycle waste-derived fluorine into reagent-grade fluorochemicals. Specifically, silver-containing ash derived from discarded conductive films serves as a reactive medium to convert waste fluorine into silver fluoride within 10 s, achieving a fluorine utilization ratio of ~90% and organofluorine removal efficiency of >99.9%. The resulting silver fluoride subsequently functions as a representative fluorination reagent for pharmaceutical syntheses. The silver residues produced post-synthesis were readily recovered and re-fluorinated into silver fluoride, maintaining a high silver recovery efficiency (>90%) and consistently high product yields over multiple cycles. This circular approach transforms waste-derived fluorine into high-value fluorochemicals, establishing a sustainable pathway toward a circular fluorine economy. Fluorine waste streams pose environmental challenges and containing valuable fluorine resources. Here the authors develop a flash-encapsulated fluorination process that transforms waste fluorine into recyclable silver fluoride reagents, coupling pollutant remediation with fluorochemical production through a rapid circular fluorine utilization pathway.","PeriodicalId":501699,"journal":{"name":"Nature Chemical Engineering","volume":"3 9","pages":"535-543"},"PeriodicalIF":29.7,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149014754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, reliance on ion-exchange membranes in current systems poses challenges to performance and scalability. Here we present a membraneless architecture that addresses these limitations by using solid-state counter-electrodes. A central obstacle in such systems is self-discharge, where sorbent intermediates undergo unintended electron transfer at the counter-electrode. We show that kinetic factors, particularly solid-state ion diffusion, rather than the thermodynamic driving forces, govern the self-discharge rate, revising conventional assumptions. Guided by these insights, we identify sodium iron phosphate as a counter-electrode for pairing with azopyridine sorbent. The system delivers stable performance over 75 capture–release cycles (350 h) and maintains efficiency under application-relevant conditions, including high current density, dilute feed and aerobic environments. Techno-economic analysis indicates a potential 28.9% reduction in capture cost compared with the membrane-based counterpart. This study establishes a scalable and generalizable framework for next-generation electrochemical carbon capture technologies. This study reports a membraneless architecture for electrochemically mediated carbon capture that uses solid-state counter-electrodes to address the limitations of ion-exchange membranes. The study also shows that unwanted charge loss is governed by ion diffusion through the solid, rather than by thermodynamics alone, offering a practical materials design principle for carbon capture and related energy technologies.","PeriodicalId":501699,"journal":{"name":"Nature Chemical Engineering","volume":"3 9","pages":"522-534"},"PeriodicalIF":29.7,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149014818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
